Difficulty Adjustment

    The difficulty adjustment algorithm (DDA) regulates the mining difficulty of a blockchain to keep it constant despite changes in hashing power on the blockchain network. The DAA ensures that miners consistently find blocks at an even rate, regardless of sudden fluctuations in hashpower. In the Bitcoin proof-of-work system, “difficulty” is a relative measure of how hard it is to guess (correctly) a new block on the network using the performed mathematical equation. The difficulty of Bitcoin is adjusted periodically based on the amount of hashing power on the Bitcoin network (in other words, the computational power required to solve the complex mathematical problems necessary to verify transactions on the Bitcoin blockchain) — the difficulty adjustment.
